Security Risks
Cybercriminals are more sophisticated than ever —
and traditional defenses aren't enough.
and traditional defenses aren't enough.
Formjacking / Magecart Attacks:
Hackers inject malicious code into checkout pages to steal card details
Unmonitored GTM Containers:
Complex Google Tag Manager setups make it hard to catch unauthorized script changes
Vulnerable Third-Party Vendors:
Even trusted tracking scripts and ad tags can leak your customers' data without warning
Performance Risks
3rd-Party Scripts Slow Sites Down
Unoptimized scripts can drag page speed and hurt UX—just a 2-second delay can raise bounce rates by 32%.
Data Leaks Start with Scripts
Even if you don’t store customer data, leaks through 3rd-party scripts can lead to brand damage and compliance risks.

Manual oversight of 3rd-party scripts can bottleneck marketing campaigns and slow collaboration with your dev team.
